OF JERSEY CITY, NEW JERSEY, A CORPORATION OF NEW FINDING-MACHINE.

Specification of Letters Patent.

Patented July '7, 1914.

Application iled October 5, 1912. Serial No. 724,018.

TQ all whom it may concern:

Be it known that I, BENJAMIN R. VAnLEY, a citizen of the United States, residing at Jersey City, in. the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in lVinding- Machines, of which the following is a specifcation.

My invention relates broadly and generally to new and useful improvements in winding machines. and more particularly machines for winding wire in coil form to form electro-magnets for use in the electrivcal arts, for instance the field magnets of motors and'dynamos. y

The object of the invention is to provide in combination with a winding spindle or mandrel upon which the coil is laid, means whereby binding or tying bands or threads may be laid between the layers of the coil while the latter is being wound so as to secure the layers and turns, particularly the outside turn of the layers, so that the turns may be held against dislodgment when'` the winding is removed-from the mandrel. The invention consists in the construction of parts and their aggroupment in operative combination to be more fully described hereinafter, and the novelty of which will be' particularly pointed out and distinctly claimed.

I have fully and clearly illustrated my invention in the accompanying drawings to be taken as a part of this specification, and wherein, j

Figure 1 is a view in side elevation of a strut-ture embodying my invention; Fig. 2 is a view in side elevation, partly in section, showing the parts in another position from that shown in Fig. 1; Fig. 3 is a section on the line 3-3 of Fig. 1; Fig. 4 is a detail sectional view on' the line 4 4 of Fig. 3; Fig. 5 is a view in side elevation of an embodiment of the invention showing the arts in an intermediate position of those s own in Figs. 1 and 2; Fig. 6 is a top lan view showing arrangement of two o the elements; Fig. 7 is a longitudinal section through a part of a mandrel showing in section a part of a winding thereon, and the manner in which the binding strip or thread is applied thereto.

Referring to the drawings by characters of reference, l designates a winding shaft or spindle adapted to be driven in any suitable manner, and 2 is a mandrel mounted on and adapted to rotate with the spindle, said mandrel being shown as polysided. and having grooved corner-pieces 3 for guiding the turns of the first layer of a winding. The mandrel is also provided with end flanges or heads 4. 5 abutting the ends of the body of the mandrel anduhaving their inner faces parallel to each other and, at right angles to the longitudinal axis of the mandrel. The spindle has bearing in one of the frame members l of a winding machine. Mounted on the spindle adjacent the outer face of each of the heads 4. 5 are circular plates G, 7 respectively, lying in parallel planes at right angles to the axis of rotation of the mandrel. .The Aplates are mounted in any suitable vmanner so as to rotate with the spindle, the inner plate G'abutting a shoulder 8 on the spindle 1 and having a pin or pins 9 adapted to enter a socket 10in the flange or head 4, while' the plate 7 is provided with a pin 11 to enter a socket 12 in the flange or head 5, a nut 13 threaded onto the outer end of the spindle serving to move the mandrel body, the flange plates 4, 5, and the plates 6, 7 toward thc shoulder 8, and clamp them against the shoulder so that all of the partsmentioned are rigidly secured together to rotate with the spindle.-

rlhe nut 14 is threaded on the end of a screw 14"'v which is connected to the mandrel body 2 by means not shown. to draw said body toward the plate 5 and thereby expand the mandrel. The construction of the collapsible mandrel and the corner pieces are not of themselves my invention, but l have employed the same as showing a type of mandrel to which my invention. as hereinafter claimed, is applicable, although l desire it to be understood that l do not limit.

myself to the particular type of mandrel shown and described.

The flange plates 6, 7 are each provided with a circumferential lateral flange 15 eX- tending toward the mandrel, and th'e inner edge of each flange is provided with inwardly projecting projections 16, preferably spaced equally from each other, around the within ythe flange of eit flanges, the projections on flan e 15 of one plate being opposite those on t e flange of the other plate. Each of the projections 16 is ehamfered at its inner end as at 16 to provide an inclined engaging face for a purpose tube presently set forth. Extending from the frame melnber 1 or other suitable support, is a guide bar 17, extendin parallel to the spindle 1, `upon which ar is slidably mounted a sleeve 18, carrying an an nular element 19, arranged concentric with the longitudinal axis of the mandrel spindle 1, and of an interior diameter greater than the outside diameter of the plates 6, 7', so that said element may be passed over said plates. A bar 20, also projecting from the frame 1l or other support, is arranged parallel to the bar 17, and is engaged by a split, or half-sleeve 21, so that said element 19 will always be moved in a straight line lengthwise of the spindle 1, and will beheld against movement laterally of the spindle. The element 19 at the part toward the outer end of the spindle 1 is provided with an inner rabbet 22, closed at its side by a ring-piece 23 secured to the face of the element 19 by means of screws 24, so that the element 19 is provided with an annular groove on its inner face. Arranged inside the element 19, which may be termed a shifting element, is arranged a strand supplyisu'pporting means consistin of a ring member 25 concentric with saidgelement 19, the plates 6, 7 and the mandrel, and of an outside diameter less than the distance between two projections 16 opposite to each other on one of the flanges 15, and less than the inside diameter of said flanges 15, so that said member 25 may be received inside the flange of said plates 6, 7. The member 25 is provided with a plurality of radially extending projections 26, of a width substantially equal tothe spaces between the projections 16, and spaced apart from each other a distance substantially equal to the width of said projections 16. The projections 26 extend into the annular groove in the inside of the element 19, so that the member 25 is movable with the element 19, and is freely rotatable relative to the same and the mandrel.

The Varrangements ofthe projections 16, on the plates 6 and 7, and the projections 26 on the member 25, is such that when the element 19 is moved to place the member 25 projections 16, 'and 26, will interlock sotllat the member 25 will rotate with the plate 6.

er 7 which it engages. The chamfered ends of the projections 16 engage the rim of the member 25 so as to center said member when itis moved into engagement with one of the plates, and facilitates such engagement, the flange 15 and the projections 16 thereon extending between the member 25 and the element 19 when the parts are engaged. It will er of said plates, theV be seen that the plates 6 and 7 constitute means for clutching the member 25 to the opposite ends of the mandrel, and while I have shown the projections 16, 26 as the means for establishing the clutch engagement, I desire it understood that I do not limit myself to the particular means shown and described as other means of engagement may be em loyed, although the one disclosed is referab e.

ounted inside the member 25 are a plurality of supply devices for the bands or strands, the same preferably consisting of flanged spools 27 journaled in inwardly projecting ears 28 on the inner sidev of the member 25, said spools havin their axes of rotation arranged circum erentially of the member 25, at right angles to the axes of rotation of the mandrel. I do not limit myself to the particular number of these devices, as there may be more or less than the number shown without departing from the intended spirit and scope of this mvention.

The members 19 and 25 are split in their peripheries to provide passages as shown at 29, 30 respectively so that when they are moved lengthwise of the mandrel during the winding operation on the mandrel,l the strand eadlng to the mandrel from the supply does not have to be disconnected, but may pa through said passages.

The operation of the above described cmbodiment of the invention is as follows: The strand :c to be wound is led from a suitable guide wheel y, and is secured to the mandrel adjacent one of the heads, say the head 4 as shown in Fig. 1, and a turn of the strand :v is laid on the mandrel. The tie bands 31 from the spools 27 are then secured to the first turn, preferably a number of strands from adjacent spools being secured at one point to said turnas shown in Fics. 1, 2 and 3, the member 25 being clutched to the mandrel at the end adjacent the first turn of the initial layer. The mandrel is then rotated, the plate 6 and the member 25 rotating with it, until a number of turns of the first layer have been completed, when the .mandrel is stopped and the member 19 with the member 25 shifted toward the opposite end of the mandrel, the strand a: passing through the passages 29, 30. It will be understood that the mandrel is stopped in such position that the passages 29, 30 will be in alinement with each other, and with the strand a: leading to the mandrel. The member 19 is moved toward the end plate until the member 25 passes inside the flange 15 and the projections 16, 26 interlock, which movement serves to carry the binding threads or bands across the turns of the layer which have been made o n the mandrel, as shown in Fig. 2 of the drawings. The mandrel is then rotated again to lay the remander of the layer already started, the

turns now being laid on top of the tie bands or threads so that the latter are bound down onto the surface of the mandrel, as shown in Fig. T, the winding being continued until the layer is completed and a part of the turns of the next superposed layer has been laid. 'lhe mandrel is then again stopped, with the openings 29, 30 in register, and :dining with the strand ai, and the member 1t) is shifted toward the opposite clutch plate or member, which carries the binding bands or threads around the finishing or outside turn of the first layer and the starting or outside turn of the second layer. The ring 25 being clutched to said opposite clutch plate, the mandrel is rotated to complete the second layer, the finishing turns being laid on top ofthe binding bands, the next (or third) layer being started, and the bands carried around the ad'acent outer turns of the second and third layers, the procedure described being repeated as desired throughout the winding at whatever turns or layers it may be desired to fasten in with the bindino' bands or threads.
